2 Claims.

My invention relates to a new and novel mounting for gold or otherprecious metals in leaf form, the present application, which is adivision of my Patent No. 1,998,506, issued April 23, 1935, beingdirected to securing metal leaf to the surface of aluminum foil,adapting the material for use in heat embossing for the ornamentation ofleather, cloth and other materials.

It has been cutomary heretofore to mount gold or other precious metalsin leaf form upon a sheet or ribbon or tape of paper, the metal leafbeing attached to the paper by a suitable adhesive such as wax.

After the metal leaf has been mounted on the paper a suitable size, suchas French varnish, is applied to the surface of the precious metal.

Upon the application of heat and pressure by a die to the material soprepared, the adhesive will be melted, permitting the paper to beseparated from the metal leaf, the size causing the metal leaf to adhereto. the surface being ornamented. If desired, of course, the size may beapplied directly to the surface of the material tobe ornamented insteadof to the surface of the metal leaf. One of the objects of the presentinvention is to mount metal leaf upon metal foil, such as aluminum, tin,lead, etc., as I have found that the use of a metal foil, by reason ofits heat conducting and non-absorbent characteristics will greatlyenhance the burnishing effect of the metal leaf to be applied to anembossed surface.

A further object of my invention is to provide a suitable supportingmedium for the metal leaf that is not destroyed during the burnishingoperation, but can be reclaimed and used again.

In the drawing: Fig. 1 illustrates one embodiment of my invention inwhich the metal leaf is applied directly to a sheet of metal foil; Fig.2 illustrates an embodiment of my invention in which a sheet of metalleaf is attached to a sheet of metal foil by an adhesive;

Fig. 3 illustrates a roll of metal foil in ribbon form with metal leafsecured directly thereto; and Fig. 4 illustrates a roll of metal foil inwhich metal leaf is secured thereto by an adhesive.

Referring to the drawing in detail and first of all to Fig. 1, Arepresents a thin sheet of aluminum foil, about the same thickness asthe paper upon which gold leaf is usually mounted. To

one surface of this sheet of metal foil is directly applied a sheet ofgold leaf or other precious metal designated B.

To the surface of this gold leaf is applied a suitable size such asFrench varnish and desig- 5 nated C.

In use, as will be appreciated, the sized surface of the leaf is applieddirectly to the leather, cloth or other surface to be ornamented and aheated die applied to the back of the foil A. The heat 10 of the diewill cause the size to attach the leaf to the surface being ornamented,whereupon the foil can be stripped or separated from the leaf andreclaimed.

I have found that the metal foil is very ad- 15 vantageous in this classof work in that it Will not curl under heat and by reason of its heatconducting characteristics, being an excellent conductor of heat, willgreatly enhance the burnishing effect on the metal leaf. 20

The use of the metal foil is of further advantage in that the step ofapplying adhesive to the foil is eliminated, the leaf in this embodimentof my invention being mounted directly on the foil.

In Fig. 2, I have shown an embodiment of my 25 invention similar to thatillustrated in Fig. 1.

A designating the aluminum foil, B the gold leaf or other preciousmetal, and C a size. In this embodiment of my invention, however, Iemploy adhesive D for attaching the leaf to the foil. I 30 have obtainedgood results employing sour milk as the adhesive D, although a materiallike paraffin gives fairly good results.

I find when employing an adhesive between the metal and the foil thatthe non-absorbent char- 35 acteristic of the foil is of advantage inthat the metal leaf adheres to the foil more satisfactorily than whenemploying a backing or mounting such as the paper, for instance,commonly employed in this art. 40

In Fig. 3 the foil F is in ribbon form as distinguished from a sheet.The metal leaf G is mounted directly on one side of this foil and thesurface of this metal leaf is coated with the size 1-1 as in Fig. 1.

In Fig. 4 the foil F is in ribbon form the surface of this foil beingcoated with an adhesive I for attaching the leaf G in ribbon form to thefoil, the surface of the leaf G being coated with a suitable size H. 50

It will be evident that in all the embodiments of my invention abovedescribed the metal leaf is mounted on a backing of metal foil, so thatthis backing will not be destroyed as in the case of paper mountings,but can be reclaimed which of course is an economic advantage.

What I claim is:

1. An article of manufacture for heat embossing comprising incombination aluminum foil, metal leaf, and an adhesive for securing themetal leaf to the surface of said aluminum foil.

2. An article of manufacture for heat embossing comprising incombination a carrier sheet of thin aluminum foil, metal leaf, anadhesive for securing said metal leaf to the surface of said foil, and acoating of size on the outer surface of said metal leaf.
